BUMPEB-BAR HANGER.

application fi le d January 8, 1924. Serial No. 684,951.

To all whom it may concern. 7

Be it known that we, VICTOR J AKOB, a citizen of Germany, and GEORGE L.Pnnnnson, a citizen of the United States, and both residents of Racine,in the county of Racine and State of Wisconsin, have invented certainnew and useful Improvements in Bumper-Bar Hangers; and we do herebydeclare that the following is a full, clear, and exact descriptionthereof.

Our invention refers to bumper bar hangers, and it has for its primaryobject to provide a bumper bar hanger having a yoke head adapted toreceive companion bumper bar clamping members.

Another object of our invention is to provide a hanger having a yokehead formed with a socketed body and forwardly extended apertured earsfor the reception of a two-part bumper bar clamp capable of oscillationupon a king bolt'seated in the apertured ears of the yoke head,together'with means in connection with the oscillatory clamp parts forsecuring them together and for maintaining the bumper bar againsttransverse thrust in either direction.

With the above and other minor objects in view, the invention consistsin certain peculiarities of construction and combination of parts, aswill be hereinafter fully set "forth with reference to the accompanyingdrawings and subsequently claimed.

In the drawings:

Figure 1 is a plan view of the same with parts broken away and otherparts in sec tion, to more clearly illustrate structural features;

Figure 2 represents a side elevation of a bumper bar hanger embodyingthe features of our invention, the same being shown associated with aspring bumper bar element, with parts in section and parts broken awayto more clearly illustrate details of construction.

Figure 3 is a side elevation of another form of our invention, the sameshowing parts constituting the hanger, to wit, the thrust arm and yokehead formed in one piece and attached to the side face of a frame-horn,and

Figure 4c is a similar elevation of still another form of our invention,showing a one piece yoke and thrust arm for the hanger bar attached tothe upper face of a frame-horn.

While this invention may be employed in connection with various types ofbumper bars, it is particularly developed for attachmg bumper bars, suchas disclosed in our allowed application for patent for improvements inautomobile bumpers, Serial No. 636,296, filed Ma-y'3, 1923, and allowedSeptember 24, 1923, and it is also obvious that while it is particularlyadapted for spring bumper'bars', it may be used in connection with anytype of bumper wherein a strap element is used and arranged to beanchored to the frame of a vehicle. 7

Referring to the drawings which illustrate certain exemplifications ofour inven tion, in spring bumpers it has beeri found by actual test thatit is highly desirable that localization of strains at thepoint ofattachment of the bumper to the frame members of the vehicle beprevented. This is accomplished by the construction illustrating certainexemplifications'of our invention.

Referring particularly to the drawings, the hanger comprises a thrustarm 1 adapted to be secured in any suitable manner to the. frame-horn ofthe vehicle. The outer end of the thrust arm is fitted into the'sooketedbody 2 of a yoke head 3. The socketed body of the yoke head is securedto the end of the thrust arm by means of rivets or bolts 3'. The yokehead has forwardly extended apertured ears 4, which ears serve ashangers for the oscillatory bumper bar clamp, the same comprising upperand lower j aw members 5'5 respectively. These jaw members are formedwith rearwardly extended, centrally aperturedflanges 66 and inturnedouter lips 7-7. The flanges of the bumper bar clamp are also providedwith alined pairs of apertures for the reception of grip and thrustbolts 88, which thrust bolts, in additionto. anchoring the jaws of theclamp together, also confine a bumper bar 9 against horizontal movementwith relation to its clamping members.

The oscillatory bumper bar clamp is pivotally mounted between the earsofthe yoke head by means of a king bolt 10, which king bolt is preferablyretained byia suitable nut and spring washer. The king bolt also passesthrough a spacing thimb'le 11, the end edges of which thimble abut theopposite faces of the flanges 6-6 of the clamp, whereby the distancebetween the same is maintained and this king bolt construction thuspermits ready oscillation of the bumper when the same is submitted toshock strain.

The friction connection between the bumper bar andthe oscillatory clampalso permit longltudinal play of sald bumper to accommodate the fiBXlOHof the same under functioning conditions.

From the foregoing description it will be .seen that a simple,economical and effective ment to the framehorn, whereby the hanger maybe adjust-ed upon the springbolt X for proper a-linem'ent and elevation,the adjustment being maintained by a bolt 12 which is secured to theframe-horn rearwardly of its frontiend, and which bolt is connected tothe rear end of the thrust arm by a suitable clamp 13. These parts,however, constitute noelement' of our present invention.

Referring now more'particularly to Figures 3 and 4, we have'illustratedin Figure 3 a one-piece hanger mechanism, wherein the shank or thrustarm is readily bolted to a side face of the framehorn, it being ofcourse understood that the yoke head 13 in this case has projectingapertured ears 14L 7 cast out in 'one'piece. In this form suitable bolts15 are utilized for securing the hanger to the side face of theframe-horn;

Referring to Figure 4, the thrust arm 16 of the hanger is ar-rangedto befitted to the top face of the horn towhich it is secured bysuitable'bolt's 17, the jaw portion having the extended cars 18,beingsimilar-inconstruction to the form just explained and illustratedin Figure 3' of the drawings. For simplicity in illustration we have notincorporated the 0s cillatory clamp member and associated parts of thebumper bar in these modified forms of hanger.

Vhile we have shown and described certain ex'eniplific'ations of ourinvention mi-- utely as to details, it is understood that the tructural'features so described may be vaied within the scope. of the claims.
